W ALL-STIRRUP'.

Specieation of Letters Patent.

Patented sept. e, 191o.

Application led May 26, 1910. Serial No. 563,538.

To all whom it may concern:

Be it known that I, PAUL KosAoK, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in Wall-Stirrups, of` whichthe following is a specification.

This invention relates to improvements in Wall stirrups or the provisionof a means for the support of bedding and furring Vstrips upon theinterior parts of building walls. In the construction of brickv or stonebuildings, blocks of wood are usually embedded in the inner side of thewalls, to which furring strips are secured so that lath may be nailedthereon for purpose of Plastering. The adjustments required forembedding these blocks, however, usually causes much expense andloss oftime, and in many instances Where artificial stone or cement blocks areemployed in Wall construction, the use of such anchors or blocks is notconvenient or practical. v

The object of the invention is to provide wall stirrups' which may beeconomically constructed of sheet metal, which may be convenientlyseated between the courses While the wall is in process of constructionand which will rovide a holding means upon the inner side of the wallfor reliably sustaining the members to be seated thereon for supportingthe lath and wall plaster.

The inventlon consists of the novel con-- struction, form andarrangement of parts as described herein and claimed and as -illustratedin the drawing, wherein,-

Figure l is a diagrammatic view-illustrating the manner of forming theWall stirrup from a rectangular sheet, or metallic plate. Fig. 2 is aplan view of the stirrup. Fig. 3 is a vertical end view thereof. Fig. 4is' a vertical side view of the stirrup. Fig. 5 is a broken away view ofa building wall in vertical section, with my newly invented stirrupmounted thereon, a bedding strip and a furring strip also being shown,the bedding strip being in section. Fig. 6 is a view showing a part ofthe inner side of a wall with the wall stirrups mounted thereon, andshowing horizontal bedding strips'` and vertical furring strips.

Referring now to the rawing for a more particular description, numeral 7indicates a metallic sheet or plate, preferably rectangular in form,which may be employed in and when the construction of the wall stirrup.It may be incised transversely between its ends on parallel and adjacentlines a b and c d, the incisions opening ilpon one of its side edges,portlon e is bent downwardly upon line b d, sol that it will be disposedat substantially a right angle to` the body of the plate, arm 8.

End portion 7 of the plate adjacent to portion e may be bent upwardly 90degrees, on line d g, to formwing 9; and, opening u on the edge oflthe'opposite end of the p ate, a short incision may be made on line z,z' longitudinally` of and midway between the sides of said plate to formen d-port-ions 7' and le; and in practice, endportions j and lc are bent90'degrees, in directions opposed to each other, to provide therespective holding-lugs or wings 10 and 11.

As thus described, wing 9, lugs' 10 and 11 and bracket 8 are disposed atright angles to body-portion lml of the metallic sheet; and the flatbody-portion m," in effect, provides two members which, for conveniencein description, are called bearing-plates 12 and 13, plate 13 having aless width than plate 12.

The wall stirrups may be economically constructed, the metallic platebeing rst incised, and then bent to ,the form'mentioned.

The may be readily mounted upon the wall whi e the courses are beinglaid, and are effective and reliable for sustaining the horizontalbedding stri s.

it provides a bracket or supporting While the wall stlrrup may be usedto advantage in almost all instances where stone or brick are laid incourses, it is herein illustrated in connection with a filled wallemploying outer and inner connected wall blocks or plates. f I vNumerals 14 and 15 indicate inner wall plates or blocks of respectivelower and upper courses of a building wall, the outer blocks of the wallbeing indicated at 16 and 16', said outer and inner blocks beingconstructed of cement or similar material and connected by any suitabletie-strips 17, adhesive lling material 18 being deposited in the spacebetween the outer and inner blocks to form the complete wall.

Bracket arm 8 is provided with a contactedge 19 disposed substantiallyparallel with lugs 1() and 11 and wing 9. After a course has been laid,as by use of blocks 14 and 16, the wall stirrup is mounted thereon, andit will be seen that lug 10 and edge 19 of bracket arm 8 will en age therespective inner and outer sides o blockllinear its upper edge,bearing-plate 12 being seated upon the upper face of saidblock.

The stirrup is so constructed that the space between bracket 8 and lugl() conforms to the thickness of the block employed, and since the twomembers mentioned have bearings upon opposite sides of the block, thestirrup will be securely held, andthe up. wardly projecting lug 11 willbe engaged by blolclk 15 of the neXt or upper course of the wa Afterblocks 15 oit the upper course have been laid, the stirrups being inhorizontal alinement as shown in Fi 6, beddin strips 20 may then bedispose horizontaly and inserted between wings 9 and the adjacent blocks15, the same being seated upon bearing plates 13, and a movement,outwardly from the wall, of strips' 20 will be prevented by said wings9.

Any desired number of stirrups may be used in connection with a singlebedding strip, and the length of the strips is not material. It will benoted that win s 8 operate as brackets; the' are dispose transversely tothe wall, an on thisaccount provide adequate supporting means forsustaining the bedding strips; and nailing of these strips to the wallis not required.

After the courses have been completed, vertical fur-ring strips 21 maybe secured to the horizontal bedding strips by nails 23, as shown inFig. 6, and an air space 22 (Fig. 5) thereby may be formed between thefurring strips and the inner side of the wall.

The stirrup thus described may have any suitable length and width, andwhere it is desired to use buildin blocks of considerable thickness, thewi th or len th of bearing plates 12 may be increase Bearingplate 13 hasa lesser width than plate 12, since it conforms to the thickness of the`beddin strip.'

Egxterior walls of solid `construction usually require the formation ofan air space between the`walls and plaster, and it is believed thatthese wall stirrups may be employed to advantage in all such instances.

Having fully described my invention, what I claim and desire to secureby Letters Patent is,-

l1. A metallic wall stirrup having a fiat body portion with Alonitudinal engaging lugs upon one of its en s projecting in oppositedirections therefrom and at right angles thereto, its opposite endhaving an upright wing disposed substantially parallel with said lugs;said body portion being incised from one of its sides upon adjacentlines substantially parallel with said upright wing, the part betweenvsaid incisions being bent downwardly andl forming a bracket' armintermediate the wing and said lugs.

2. A wall stirrup having a flat rectangular lbody-portion withoppositely-disposed lugs upon one of its ends, its opposite end belngprovided with an upset wing, said body portion having incisionsextending longitudinally from one of its sides, the part between saidincisions being bent downwardly and providing a bracket arm with acontact-portion disposed substantially at right angles to said bodyportion in a plane between the wing and said lugs. 3. -A wall stirruphaving a flat rectangular body-portion with oppositely-disposed lugs'upon one of its ends, its opposite end being provided with 'an upsetwing; said body-portion having adjacent parallel incisions formedtherein and extending longitudinally from one of its sides, one of saidincisions being at the junction of sald wing with said body-portion, thepart vbetween said incisions elng bent downwardly and providing abracket arm with a contact-portion disposed substantially at rightangles to said `body-portion in a plane etween the wingand said lugs.

In testimony whereof I have atxed my signature in presence of twowitnesses.

PAUL KOSACK.
